Some illnesses are caused by the chemicals and conditions we expose ourselves to. Among the scariest diseases, however, are the contagious ones. While medical advances, improved hygiene, and sanitation have almost eliminated some "bugs," others are fighting back and developing strains resistant to our medicines. Infectious diseases caused by bacteria, viruses, and parasites remind us that we must be ever watchful for outbreaks.
